I’ve mentioned a couple of open source components for creating stacked folders, and vertically stacked views.
Here’s a library from David Bonnet enabling you to easily stack your controllers in a style similar to that of the Evernote Food app.
You simply supply an array of controllers or navigation controllers, and you can define the space between each individual sheet,and GDSheetController adjusts to display each sheet.
Here are a couple of images showing GDSheetController in action:
You can find GDSheetController on Github here.
A nice stacking control.
